Thanks for the explanation it was most helpful and promises to fix a few things for some controllers.. but here's a minor bit of passing bad news - quite a few older ATA controllers can't issue DMA transfers that are not a multiple of 512 bytes without crapping themselves (eg READ_LONG). Guess we may need to add ap->i_do_not_suck or similar 8) On the bright side I believe the Intel ICH is the only one with this problem (and a workaround) which is SATA capable 8) Alan - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
